React JS is well known for creating cross-platform mobile and web applications. It is an open-source JavaScript library (prewritten code used for repetitive common tasks) that can be assembled along with various frameworks for improved performance. React JS should be the first choice if you wish to develop single page applications. Often hybrid developers make use of React JS to create larger web applications, (along with AJAX) that require changing data within the content placeholder without page reload. Experienced programmers have a reason to use React in their web applications – highly performant, scalability and code simplicity.
The Role of JS in React
JavaScript is known to make frontend interactive, to make the entire static things dynamic, and to add in a dash of animation-graphics-photos-slideshows-interactive forms to the web pages.
Why is ReactJS Used By Javascript Developers?
React constitutes a JS library that is used to build user interfaces which are the collection of on-screen menus, search bars, buttons, forms, dropdowns, multi-line textboxes in a website or app. React often comes with JSX and Virtual DOM features that add to the overall JavaScript appeal.
Are React Native and ReactJS different?
Yes, React Native and React JS differ slightly with JavaScript in action in the latter making it highly performant, fast and interesting. This makes fast webpage rendering, leading to dynamic user input. React’s Native counterpart gives a native appearance and functionality to the cross-platform mobile app. ReactJS simply renders views or the user interface part of the web applications.
Can We Use React JS Code with React Native?
Yes, we can. The entire app created in React JS can be converted or put to use in React Native. You simply need to follow the React Native Architecture, develop your UI using React Native components, and write every component separately for a mobile app and web app.
What Kind Of Applications Can We Create with ReactJS?
Here are examples of some applications built with React JS:
Calculator, Emoji Search, GitHub Battle App, React Powered Hacker News Client, Pokedex, Shopping Cart, Progressive Web Tetris, Product Comparison Page, Hacker News Clone React/GraphQL etc.
What Reasons Make ReactJS The Best Choice to Create Applications?
We already know that JS is the reason behind converting a static thing to a dynamic one in the web application.
- Easy To Understand and Use: With this, React beats all competition being very easy to understand and easy to use.
- Code-Reuse: The same code can be used across platforms. React Native focuses on the user interface and can be coded along with frameworks to provide the right value.
- JS Engine Makes It High On Performance: React comes with fast client platforms and a JavaScript engine, the tree-structured extensive DOM manipulation does have a huge impact in case of any changes to the application.
- Virtual DOM: The presence of virtual DOM provides higher performance and a cleaner user experience all around.
- Developer Tools: React also comes along with developer tools to design, debug, examine and edit the current properties and state of the app.
On Which Points Can We Map the Potential of ReactJS as the Best Platform?
| Differentiation | ReactJS |
| How React JS came into being? | React was developed as a framework to develop and design interactive UI for each state of the application. It is good enough to create a single page and mobile apps. |
| Initial release | May 2013. |
| Adoption across industries | Netflix, Facebook, New York Times, Yahoo Mail, Dropbox, Khan Academy, WhatsApp, Instagram and Codecademy |
| Integration | ReactJS focuses on one-way binding taking a bit longer than Vue.js to develop applications. |
| Size and Load Time | React JS features Chrome DevTools that increase performance, easy code splitting to optimize the application. It also comes with some inbuilt functions like pre-fetching, service workers, bundle analysis etc. to improve the overall application performance. |
| Complexity | Slightly high |
| Flexibility | It is rigid |
| Components and Directives | It comes with 5 components and 3 directives – to add and encapsulate app behaviour. |
| Development Time | Higher |
| Suitability | To develop mobile apps and single-page web applications. |
| Backward Compatibility | Yes |
| Architecture | Component-based architecture that saves time. Model View Controller (MVC) |
| Code Inheritance | ReactJS makes use of composition instead of inheritance to reuse the code amongst components. |
| Experience | It is 7 years old and is still popular (updated 2020) |
| Stability | Yes |
| Community Support | Yes |
| Documentation | It comes with helpful resources |
| CodeBase | Heavier |
| Coding Speed | Slower but agreeable |
| Reactivity | Reactjs can be made fully-reactive and functional with the help of reactive programming and libraries like Redux. |
| Component-Based | Yes – independent and reusable bits of code. |
| Routing | Yes, React Router facilitates this. |
